java的动态绑定 与静态绑定

一、

java的动态绑定都是针对 类的方法的  与 类的变量无关；  类的成员变量都是静态绑定，即根据其声明决定

二、

java当中的方法只有final，static，private和构造方法是静态绑定；其余的都是动态绑定

例如：

public class Father{
	protected String name = "Father";
	
	public Father(){
		System.out.println("in Father()");
	}
	public void fun(){
		System.out.println("in fun for father");
	}
		
	public static void staticFun(){
		System.out.println("in static for father");
	}
}

public class Child extends Father{
	protected String name = "Child";
	
	public Child(){
		System.out.println("in Child()");
	}
	
	public void fun(){
		System.out.println("in fun for child");
	}	
	
	public static void staticFun(){
		System.out.println("in staticFun for child");
	}
}

public class MyTest {


	public static void main(String[] args){
		Father f = new Child();
		
		System.out.println("-------------------------------");
		
		System.out.println(f.name);
		f.fun();
		f.staticFun();
		
	}
}

in Father()
in Child()
-------------------------------
Father
in fun for child
in static for father
